IMPROVEMENT iN icor'rowelws.

Specication forming part of LettersPatent N0. 4,175, dated March 3,1874;,application lcd January 17, 1874.

To all whom it may concern:

Be it known that I, EDWARD BUCKLIN, J r., of Pawtucket, in the county ofProvidence and State of Rhode Island, have invented a new and valuableImprovement in Cotton-Gills 5 and l do hereby declare that the followingis a full, clear, and exact description of thefconstruction andoperation of the same, reference being had to the annexed drawingsmaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawing is a representation of a longitudinal sectionalview of my cottongin. Fig. 2 is a plan, and Fig. 3 a transversesectional, view ot' the same. Figs. 4, 5, 6, and

7 are details of the saine.

This invention, 'has relation to machinery which is designed forseparating seeds from cotton, my object being to perform this workwithout the use of saws, which, it is well known, injure the cotton bersmore or less. llIy invention consists, mainly, in the employment, in anovel manner, of reciprocating combs and a holder, with feeding ortaking-oft' rollers, whereby the seed-cotton will be tlrmly held over anopening through the-feed-table, while the combs remove the seed from it,one comb acting to press out the seed, while the other comb clears it ofadhering cotton, as will be hereinafter more fully explained. Theinvention further consists in novel mechanism for actuating theseparating-combs and the reciprocating holder.

The following is a description of my invention:

In the annexed drawings, A designates the frame of the machine, on whichis an inclined table, a, that supports and holds in place a hopper, B,throughv which latter the cotton is fed to the separators. C C are tworollers properly journaled in the cheeks of frame A, and arrangedhorizontally, for feeding or drawing in the cotton and discharging itover a lixed apron, b. The upper roller C may be clothed with leather,or some other suitable material, and the lower roller C maybe serratedlongitudinally, similar to the drawin grollers 7 of spinning-machines.The upper roller C is held in contact with the lower one,

C', by means of springs in the journal-boxes. D is the maindriving-shaft, carrying on one end a spur-wheel, c, and, between thecheeks of frame A, an eccentric. Spur-wheel c engages with anotherspur-wheel, c', which is keyed on the shaft of roller C', on which shaftis also keyed a spur-wheel, cl, which gears with a spur-wheel, d', on ashaft, E. Shaft E carries an eccentric, c, which, by means of a yoke andconnecting-rod, f, communicates a reciprocating motion to two arms, g g,which vibrate on a horizontal shaft, F. Arms g-g are connected by rodsl1J h to a vertical]y-reciprocating head, Gr, to which aseparating-comb, G, is secured, the teeth of which are on its lower edgeand may be constructed in any suitable manner. The head G is constructedwith vertical slots through it near its extremities, through whichscrews ifi'pass, which loosely attach the head to a pressure-plate, J,the ends of which are guided by vertical slots through side bear-Ving-:plates H. Beneath the table a, and in close relation to its bottomside, is a reciprocating comb, a, which is secured to a slide, N, thatworks forward and backward in guides on the bottom of the table a, andreceives its movements from the eccentric i', through the medium of ayoke and connecting-rod, i".

If desirable, the two combs (SH-a may be adjustably secured to theirrespective plates.

In feeding the cotton, with seed and leaf in it,` between the rollers GG", it passes over a slot, s, through the table a, which slot is inclose relation to the rollers and directly below the comb G. The firstoperation is the descent of the plate G, which presses the cotton whichis between the said slot s and the rollers O C down iirmly on the tablea, and holds it there. Thecomb G then descends through slot s andpresses out the seed, and as the comb G ascends the comb n advances toit and clears .the cotton from its teeth. During these operations thecleaned cotton is being discharged over the apron b by the rollers O C.It will be observed that the teeth of the comb G do not tear or in anymanner injure the fibers of the cotton, but simply pass down through andseparate the seed from it while it is being held by the plate J.

The uished sliver is prevented from being Wound around the upper rollerC by means of a vertically-rcciprocating beater, L, the arms of Whichare fast on an oscillating` shaft, L. This shaft L' may be oscillated bymeans of a crank-arm, P, connecting-rod P', and a wrist pin, p, on thespur-Wheel.

That I claim as new, and desire to secure by Letters Patent, is-

l. Reciprocating` combs Gr n and a pressureplate or holder, J combinedwith takingbff rollers, substantially as described.

2. The pressure-plate or holder J loosely attached to arertically-reciprocating head, Gr,

so that it will press the sliver 011 the table ct in front of theopening s, previous to the operation of the comb Gr on the cotton-seed,substantially as described.

3. The combination of the holder J and stripping-comb a with aSeedseparating comb, G', substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two Witnesses.
